Thanks, Rolando.

This makes sense now. While speaking about PHD2 guiding, is there a short summary of PHD2 starting settings recommended for this mount ? My friend had suggested that I probably should use hysteresis guiding algorithm for DEC axis instead of the default resist-switch, also use lower aggressiveness of RA hysteresis algorithm of 60 instead of 70.

Thanks,

Leo

Orienting the camera with respect to RA/DEC is not absolutely necessary. It does make calibration somewhat easier to understand and eliminates one more variable when trying to solve a problem.

Rolando,

Thank you. I will check the guiding camera for orientation. It is good to know that the mount works best at 1 x guide rate, it's not what I have been using but in this case I actually tried both, 0.5 x and 1 x. I will definitely change it permanently to 1 x. The problem happened out of nowhere, last time I imaged everything worked fine and than I spent several weeks without imaging because of the weather and then last night this happened.

I didn't know the orientation of the guide camera mattered, I will definitely double check. 

Thanks again!
